(1) Field of the Invention
The disclosure relates to a bus structure, and more particularly to a bus structure utilized in a scanning device.
(2) Description of the Prior Art
In order to transmit electric signal or energy, bus structure is widely used in electric device, for example, within a foldable electric device, a bus structure is often utilized to couple one separate part to the other, or to a movable part. Especially when the electric signal or energy is transmitted between two relatively motioning parts of an electric device, the flexible feature of a bus structure enables the electric device to operate smoothly.
The structure of a scanner is schematically shown in
As schematically shown in
The tube lamp 4 is designed to move forward and backward within the scanner 2, however, if the stacked first soft bus 1002 and second soft bus 1004 are adhered each other will double the thickness of the bus structure 10, so the flexibility of the bus structure 10, is reduced, in addition, the traction between the soft buses may further hinder the movement of the tube lamp 4. If the stacked first soft bus 1002 and second soft bus 1004 are not adhered each other, the first soft bus 1002 and second soft bus 1004 will contact each other to broke these soft bus 1002, 1004. Furthermore, because of the close attachment of the soft buses, the signals transmitted in the soft buses may interfere with each other, and the quality of the output image will thus be reduced.
Due to the disadvantages mentioned above, as the trend of slim design, it is very important to shrink the dimension of a scanner, and it is fundamental to improve the foregoing deficiency.
Accordingly, it is one object of the present invention to propose a bus structure which provides electricity and/or electronic signal between movable electronic parts within an electric device. The present invention can make the movable electronic part move with less traction than traditional one, i.e., the movable electronic part which coupled to the bus structure according to the present invention can move much more easier than the traditional one. In addition, the structure of the bus structure according to the present invention can shield mutual interference from the stacked part of the bus structure, so the image signal through the bus structure can be transmitted without mutual interference, and the resulted image quality of the electric device can be greatly improved.
The present invention relates to a bus structure utilized in a scanning device, the bus structure includes a plurality of soft buses and at least one soft separation layer. The bus structure splits in longitude to form the plurality of soft buses, and the plurality of soft buses are stacked and side by side arranged. Each soft separation layer is sandwiched between every two adjacent soft buses. Each of the plurality of soft buses includes a set of signal wires, each set of signal wires includes a plurality of signal wires which are parallel and side-by-side jointed in longitude. Thus every strip of soft bus are shield from each other by at least one soft separation layer.
In one preferred embodiment of the present invention, the plurality of soft buses are side by side placed, and every two adjacent soft buses are stacked together with a soft separation layer sandwiched therebetween. According to one of the preferred embodiments of the present invention, the soft separation layer can be made of foam material that possess smaller coefficient of fiction to the surface of soft bus than that between the soft buses, besides, the soft separation layer adheres to one of the two adjacent soft buses. So the traction from the moving bus structure according to the present invention is greatly reduced.
Accordingly, the bus structure in the present invention utilizing the soft separation layer makes it easier and smoother for the movable electronic part to move freely, and the adoption of signal wires greatly reduce the interference (such as cross talk) to the image signal, thus the quality of the resulted image is greatly improved.
The present invention will now be specified with reference to its preferred embodiment illustrated in the drawings, in which
As schematically illustrates in
As shown in
The first soft bus 3202 and the second bus 3204 are stacked side by side with the soft separation layer 34 sandwiched between thereof. In one of the preferred embodiment of the present invention, the soft separation layer 34 adheres to one of the soft buses 3202, 3204, besides, the coefficient of fiction between the surface of the soft separation layer 34 and the soft bus is smaller than that between the soft buses. The soft separation layer 34, in this preferred embodiment of the present invention can be made of foam material. Furthermore, according to one preferred embodiment of the present invention, the soft separation layer 34 is designed to adhere to one of the soft buses 3202, 3204, and only contact the other, thus making the bus structure 32 move without obstruction which resulted from the traditional bus structure.
In one of the preferred embodiments of the present invention, the sandwiched soft separation layer 34 can be formed in one piece with the soft buses 3202, 3204. In the other preferred embodiment, the soft separation layer 34 can be formed in several sections, which are separately manufactured in a process other than the process forming the soft buses 3202 and 3204. In this embodiment, the soft separation layer 34 is formed in several sections, so the whole structure, i.e., soft buses 3202 and 3204 and the sandwiched soft separation layer 34, have better flexibility.
According to the preferred embodiment of the present invention, because the bus structure 32 utilizes the soft separation layer 34, which is sandwiched between these adjacent soft buses 3202 and 3204, therefore the electronic part 30 can move with less traction from bus structure than the traditional one. In addition, the signal wires between the first soft bus 3202 and the second soft bus 3204 successfully isolate the interference from each other, thus the bus structure 32 according to the present invention can transmit signal with less interference (such as cross talk) and the resulted image quality is greatly improved.
While the preferred embodiments of the present invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the present invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the present invention.
